Section 329IAC9-2.1-1. Upgrading of existing UST systems

   (a) All existing UST systems shall comply with one (1) of the following requirements no later than December 22, 1998:

(1) New UST system performance standards under 329 IAC 9-2-1.

(2) The upgrading requirements under subsections (b) through (d).

(3) Closure requirements under 329 IAC 9-6, including applicable requirements for corrective action under 329 IAC 9-5.

  (b) A steel tank must be upgraded to meet one (1) of the following requirements:

(1) A tank is upgraded by cathodic protection and the cathodic protection system meets the requirements of 329 IAC 9-2-1(1)(B)(ii) and 329 IAC 9-2-1(1)(B)(iii), and the integrity of the tank is ensured using one (1) of the following methods:

(A) The tank is internally inspected and assessed to ensure that the tank is structurally sound and free of corrosion holes prior to installing the cathodic protection system.

(B) The tank has been installed for less than ten (10) years and is monitored monthly for releases under 329 IAC 9-7-4(4) through 329 IAC 9-7-4(8).

(C) The tank has been installed for less than ten (10) years and is assessed for corrosion holes by conducting two (2) tightness tests under 329 IAC 9-7-4(3) as follows:

(i) The first tightness test must be conducted prior to installing the cathodic protection system.

(ii) The second tightness test must be conducted between three (3) months and six (6) months following the first operation of the cathodic protection system.

(D) The tank is assessed for corrosion holes by a method that is determined by the commissioner to prevent releases in a manner that is no less protective of human health and the environment than established in clauses (A) through (C).

(2) A tank is upgraded by internal lining and the following requirements are completed:

(A) The lining is installed under 329 IAC 9-3.1-4.

(B) Within one (1) year after lining and every five (5) years thereafter, the lining and tank are internally inspected and found to be structurally sound with the lining and tank still performing in accordance with requirements under 329 IAC 9-3.1-4.

(C) The tank may be lined one (1) time during the service life to meet the upgrading requirements of this subsection.

(D) If the lined tank cannot meet the performance standards under clause (B), closure of the tank according to 329 IAC 9-6 is required.

(3) A tank is upgraded by both internal lining and cathodic protection, and the following requirements are completed:

(A) The lining is installed under 329 IAC 9-3.1-4.

(B) The cathodic protection system meets the requirements of 329 IAC 9-2-1(1)(B)(ii) and 329 IAC 9-2-1(1)(B)(iii).

(4) A tank is upgraded by a method that is determined by the commissioner to be no less protective of human health and the environment than the methods specified in subdivisions (1) through (3).

(5) The tank must comply with one (1) or more of the following:
